C, Cygwin and compiling drand and srand

I have C code that I am trying to compile in Cygwin and which contains functions drand()

andsrand()

... I had Windows Vista with Cygwin installed and the code seemed to compile just fine, but my computer crashed and I had to get a new one. The new computer has Windows 7 64-bit. I had a few problems loading Cygwin, but finally managed to do so by only selecting a few packages and then tried to get the rest that I needed. The problem is that I don't have the help that I installed on my other computer, so I don't know what packages I really need, so I was just guessing (all gcc tags), but I shouldn't have one. you need to shit and work. If anyone could point me in the right direction and also maybe just let me know which packages I need to compile C so I can check that I have everything, which would be great.

Thanks a lot for any help.

Sorry, that was a lot of words!

srand()

and the drand()

functions are part of the library <stdlib.h>

and must be included in the cygwin gcc-core package. If not, then I think it will be an issue with 64bit cygwin packages or OS. Since you mentioned that you are having problems with the installation, I am guessing that something went wrong in the process.

drand

is not guaranteed to be part of the standard C library. That being said, I first installed all the corresponding stdlib and gcc libraries. I cannot think of a separate drand library.
